Here’s the good news: Adding these foods to your diet may help to increase your odds of a successful slumber.

Fish

Most fish—and especially salmon, halibut and tuna—boast vitamin B6, which is needed to make melatonin (a sleep-inducing hormone triggered by darkness), according to an article published in the Annals of the New York Academy of Sciences.

Jasmine rice

When healthy sleepers ate carbohydrate-rich suppers of veggies and tomato sauce over rice, they fell asleep significantly faster at bedtime if the meal included high-glycemic-index (GI) jasmine rice rather than lower-GI long-grain rice, in a study published in the American Journal of Clinical Nutrition. While the authors aren’t sure how it happened, they speculated that the greater amounts of insulin triggered by the high-GI meals increased the ratio of sleep-inducing tryptophan relative to other amino acids in the blood, allowing proportionately more to get into the brain.

Yogurt

Dairy products like yogurt and milk boast healthy doses of calcium—and there’s research that suggests being calcium-deficient may make it difficult to fall asleep.

Whole grains

Bulgur, barley and other whole grains are rick in magnesium—and consuming too little magnesium may make it harder to stay asleep, reported theJournal of Orthomolecular Medicine.

Kale

Dairy products are well-known calcium-rich foods. But green leafy vegetables, such as kale and collards, also boast healthy doses of calcium. And research suggests that being calcium deficient may make it difficult to fall asleep.

Bananas

Bananas, well-known for being rich in potassium, are also a good source of Vitamin B6, which is needed to make melatonin (a sleep-inducing hormone triggered by darkness), according to an article published in theAnnals of the New York Academy of Sciences.

Chickpeas

Chickpeas boast vitamin B6, which is needed to make melatonin (a sleep-inducing hormone triggered by darkness), according to an article published in theAnnals of the New York Academy of Sciences.

Fortified cereals

Fortified cereals also boast vitamin B6, which is needed to make melatonin (a sleep-inducing hormone triggered by darkness), according to an article published in the Annals of the New York Academy of Sciences.
